How did the 1947 partition change Calcutta’s economic connections with its hinterland?

The 1947 partition of Bengal served as a significant economic setback for Calcutta (now Kolkata). By separating the city from a large portion of its former hinterland—which became East Pakistan, now Bangladesh—the partition disrupted established trade networks and access to resources.12

This geopolitical shift had several direct consequences:

• Industrial Decline: The city’s manufacturing sector, particularly its vital jute-processing industry, suffered due to the loss of its eastern hinterland, which had been integral to its supply chain and market reach.2
• Transportation Disruption: The division of the region, combined with the deterioration of river channels, severely hampered local river transportation, which had historically been a key component of the city's connectivity.3
• Social and Economic Strain: The influx of millions of refugees from East Pakistan exacerbated existing overcrowding and social instability, further straining the city's resources and contributing to long-term economic stagnation.1

These factors collectively diminished the city's economic dynamism, leading to a period of decline in industrial productivity that persisted in the decades following independence.12
